template< bool OtherConst > requires std::sentinel_for<ranges::sentinel_t<Base>, ranges::iterator_t</*maybe-const*/<OtherConst, V>>> friend constexpr bool operator==( const /*iterator*/<OtherConst>& x, const /*sentinel*/& y ); |  | (since C++23)

Compares the underlying iterator of x with the underlying sentinel of y.

Equivalent to: return x.current_.back() == y.end_, where `current_` is underlying array of iterators in x, and `end_` is the underlying sentinel in y.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `adjacent_view::sentinel<Const>` is an associated class of the arguments.

The `!=` operator is synthesized from `operator==`.

### Parameters

x | - | iterator to compare
y | - | sentinel to compare

### Return value

true if the underlying iterator stored in x is the end iterator.
